We manufactured and delivered the 525 kV HVDC cable system, jointed and terminated the onshore cables.
NKT´s cable system constitutes the part from the Danish shore to the power grid substation in Revsing.
We manufactured the 525 kV HVDC MI onshore cables during two years at our excellent facilities in Karlskrona, Sweden. The factory runs completely on renewable electricity. Despite the Covid-19 pandemic challenges, 113 drums with a weight of 80 tonnes each were successfully produced, tested and transported on vessels to Esbjerg in Denmark.
During one year two teams with six persons each, worked around the clock to joint and terminate
NKT´s part of the cable system. MI jointing process was performed by certified staff in specially designed housings at controlled temperature and humidity. All cable drums lengths were delivered, connected and tested by NKT and the high focus on health and safety within the project resulted in zero LTI (Lost Time Injuries).
The efficient project execution was generated by good collaboration based on strong relationship and trust between all involved parties. We completed our scope within planned budget and ahead timeline than contractually required. The fact that we were selected as partner by Energinet and National Grid is a recognition of our technical expertise and long HVDC experience.
